There's no problem with acetone and some will even add it, especially with zero nitro fuels. Shell methanol has it as standard at 3%. I'm no expert on nitro but I believe that pure nitro can become shock sensitive which is why a dye is added to show if it's still safe or not. Diluting pure nitro with a tiny amount (maybe 1%?) of methanol stops it becoming shock sensitive. Or so I've read.....
The dye is yellow and is required in all racing fuel in the US. Not sure if the methanol helps or not. But it buying nitro with a purity higher than the indicator percentage, then there is a greater chance that it would become shock sensitive. Unless I had equipment to take care of this I would worry about the fuel not having the indicator.
